Description
先了解基本的字符串类型：
整数：int
字符串：str
布尔值： bool
列表：list
元祖：tuple
字典：dict
我这里是用了isinstance函数做判断。
isinstance完整的语法是isinstance(object,classinfo)
object这里输入需要进行判断的对象；
classinfo这里输入类型，比如：int , str；
然后函数会返回True或False。
示例：
a = 1
print(isinstance (a,int))
#输入这个会输出True，因为1属于整数；
print(isinstance (a,str))
#输入这个会输出False，因为1不是字符串；
print(isinstance (a,(str,int,list)))
#输入这个会输出True，因为1属于(str,int,list)三种属性中的int。

Research direction
The issue body discusses Python's isinstance function and basic types, but it names no repository file, test, or documentation entry point. First clarify whether this is meant to become or improve a specific learning document; completion cannot be defined from the current issue alone.
